Building a weatherproof electricity distribution network progresses on schedule and improves the reliability of electricity distribution to customers
Caruna's projects to build a weatherproof electricity network progressed as planned in the group's network areas across Finland. The investments improved the reliability of electricity supply for some 13,000 customers by replacing old electricity network with underground cables, increasing network automation and clearing trees in the vicinity of overhead lines. In January-June, approximately 1,750 kilometres of the network was placed underground to protect it from the elements and the network cabling rate went up to 56 per cent.
Reliability of supply rate was 99.99 (99.98) per cent. The highest number of supply interruptions was caused by the storm known as Aapeli in January, during which the highest number of customers simultaneously affected by an interruption of supply was 28,900. The investments to improve the reliability of supply have reduced both the number of electrical faults and the time taken to rectify them. During the storm known as Tapani in 2011, there were more than 200,000 Caruna customers simultaneously without electricity and the day after the storm, there were still more than 100,000 customers without electricity.
The total volume of supplied electricity between January and June decreased slightly due to a warm beginning of the year and was 5.0 (5.2) TWh in the distribution network and 1.4 (1.5) TWh in the high voltage distribution network.
The Group’s net sales amounted to EUR 240.6 (230.5) million, showing a growth of 4.4 per cent compared to the same period last year. Net profit for the period was EUR 10.9 (net loss EUR -6.8) million. The investments in electricity networks were EUR 80.3 (127.8) million, representing 33 per cent of net sales.
“Cabling and other measures to secure weatherproof electricity distribution to our customers are starting to pay off, and we are progressing on the schedule set by the legislator on achieving the reliability of supply commitment. The network area of Caruna Oy particularly includes sparsely populated areas where it is more cost-effective to use other measures than cabling to achieve the requirements on uninterrupted electricity distribution. We are currently investigating alternative technical solutions to reach the required reliability of supply at a lower cost compared to cabling,” says Tomi Yli-Kyyny, CEO of Caruna.
New digital services for customers
Between January and June, Caruna launched several services to make digital interaction easier for customers, such as the mobile app Caruna+ where customers can monitor their energy consumption and view their contract and billing information. In May, Caruna launched a digital service called Caruna Markkinapaikka where customers can find information about the service offerings of various solar panel providers, compare product and price information and select the solar panel provider that suits them best. There are currently over 20 solar power partners participating in Markkinapaikka. The plan is to expand the service to other fields, such as charging solutions for electric cars.
The number of small-scale producers of electricity in Caruna‘s network saw strong growth between January and June, and during this period, 1,100 new solar power producers were connected to Caruna‘s networks. By the end of the period, the number of small-scale producers was 5,200 (3,100).
Joint construction of electricity and fibre-optic networks kicks off
Early in the year, Caruna and Telia announced an agreement on cooperation to install a fibre-optic network in the ground along with electric cables. The planning work for the first joint construction sites in Rusko and Raisio in Southwest Finland was started in the spring, and the construction of the networks began in late summer. The joint construction of electricity and fibre-optic networks is the first joint project of this scale in Finland.

Caruna distributes electricity and maintains, repairs and builds a weatherproof electricity network for its 680,000 customers in South, Southwest and West Finland, as well as in the city of Joensuu, the sub-region of Koillismaa and Satakunta. In order to guarantee a reliable electricity supply to its customers under all circumstances, Caruna supervises its network 24/7. A weatherproof smart electricity network also provides a well-functioning energy system for the future when digital services increase, the traffic is electrified, and the consumer becomes a producer of energy. www.caruna.fi/en
